[asterisk-users] conf files for dahdi

[sean darcy]

upgrading from zaptel to dahdi, with a TDM400P:

Is /etc/dahdi/system.conf the same as /etc/zaptel.conf? As I read the 
system.conf.sample, no echo canceller need be specified if there's a 
hardware ec. Can I just rename zaptel.conf?

What about zapata.conf? Is this just renamed 
/etc/asterisk/chan_dahdi.conf? Or zapata-channels.conf? Or just left alone?
